Abstract (en)
[origin: US2021033489A1] A device for measuring the optical effect of an ophthalmic lens, in particular a spectacle lens, includes a display system, an image acquisition system, and a computer unit. During measurement, the lens is arranged in a measurement volume of the device. The display system displays a test structure and the image acquisition system acquires image data of the test structure from multiple viewpoints using imaging optical paths which pass through the lens. The computer unit determines the three-dimensional shape of the lens on the basis of the image data and calculates an optical effect of the lens on the basis of its three-dimensional shape. A corresponding method and computer program are also disclosed.
